Additional Information:

Hello there @tup0lev please accept my apologies for this issue. Could you please try installing the beta or Nightly version of Brave on your device to see if Brave recognizes your proxy server? You can install them from here https://brave.com/download-beta/

Also please try using a different browser to see if your proxy server is detected there.

Be waiting for your response.
